Single quotes for start/end time strings causing "Invalid duration specification" error

[IA21]

The command ffmpeg -i in.mp3 -ss '00:13:10' -to '00:17:09' out.mp3 gives Invalid duration specification for ss: '00:13:10' error. Removing the quotes works. Its possible my ffmpeg version is old and maybe quotes are supported in later versions. In this case, maybe adding another checkbox for quotes around timestamps be helpful?

Hmm, that's strange. It almost seems like something strange is happening with your shell, not this command specifically. But that might be wrong!

What shell are you using, and on what operating system? Do you see quote issues with other commands?

Ah, okay.

I think it should switch to double quotes if we detect that you're on Windows. If you're willing to make a pull request, I'm happy to review it!

I will try if I can find the time. But I have not made a proper pull request before so please bear with me if/when I submit something silly 😅

All good!
